Abstract：
In this paper the structure of the wide resonance θ(1720) produced in J/ψ hadronic decays is studied by using the generalized moment analysis.Since the production ratio of the f'₂(1525) is very small in the process J/ψ→ωθ(1720) we may neglect the influence of the f'₂(1525).Whereas the production ratio of the f'₂(1525) is larger in the process J/ψ→φθ(1720),we must consider the coherence effects of the f'₂(1525).From the studies of the two processes and the corresponding J/ψ radiative decay we are able to understand the structure of the wide resonance θ(1720) better.
